Prime Line Products B 704 Screen Door Tension Spring

Product Description

The PRIME LINE PRODUCTS B 704 is a steel ball bearing tension spring designed for screen door applications. This component provides the closing tension that keeps screen doors properly seated in their frames, functioning within the door's operating hardware. Each package contains 6 springs, making it a practical supply for service calls or multi-door installations. Weighing 0.89 pounds per package, this unit is compact and easy to carry on the job. The ball bearing construction supports smooth, consistent spring action over repeated use cycles.

This tension spring is intended for use on Columbia brand screen doors. It fits into the standard tension spring mounting location found on these door systems and is a direct replacement for worn or broken original hardware. The 1-inch specification refers to the spring size, which corresponds to the fitment requirements of compatible Columbia screen door assemblies. Installers working on residential screen door service and repair will find this a straightforward drop-in replacement.
